Chlorine & salt water can discolour and tarnish earrings. Avoid wearing them while showering, swimming or exercising.

Avoid all chemical contact.

Polishing your earrings will help to maintain shine and avoid tarnishg.

Note: When silver and gold are exposed to air and the atmosphere, it causes a chemical reaction that creates something called Silver Sulphate. This sulphur creates the darkening referred to as tarnishing.
